If you had all primes

There have been endless threads over the years about nikon, vs cannon, vs Carl Zeiss, vs Other prime lens comparisons. I am not going to ask the standard "Which is the best X mm lens?" question. Instead lets imagine you have all of them.

Which lens makers lens would you use for which purpose, and why?

The same reason can not be used for more than 1 lens per focal length, but it can be used for functionally different focal lengths.

Here are some general strengths/weaknesses i see for different lenses:

Points (higher number is better)

PRICE

Nikon - 0

Zeiss - 1

Sigma - 2

AF

Nikon/Sigma - 1

Zeiss - 0

Quality of MF

Nikon/sigma - 0

Zeiss - 1

Construction/build quality

Nikon - 1

Sigma -0

Zeiss - 2

IQ

Nikon/Zeiss - 1 varies from lens to lens

Sigma - 0

Which lens would you choose for which application in real life? For example I'd take a Zeiss lenses on a road trip vs nikon since they are tougher built or Sigma since they are generally cheaper to replace. But I'd take a nikon to a party since AF works faster than my hand. I'd probably choose Zeiss for studio work.

Your turn; feel free to come up with other use scenarios than just mentioned above.

Looking forward to reading your comments.

EDIT

In usage example above i made blanket statement across all focal lengths; feel free to choose different lenses of different focal lengths even if they share the same application like landscape...
